High performance bilayer-graphene Terahertz detectors
Davide Spirito, Dominique Coquillat, Sergio L. De Bonis +7
We report bilayer-graphene field effect transistors operating as THz broadband photodetectors based on plasma-waves excitation. By employing wide-gate geometries or buried gate con…
Controlling Sub-nm Gaps in Plasmonic Dimers using Graphene
Jan Mertens, Anna L. Eiden, Daniel O. Sigle +9
Graphene is used as the thinnest possible spacer between gold nanoparticles and a gold substrate. This creates a robust, repeatable, and stable sub-nanometre gap for massive plasmo…
Effects of Electron-Electron Interactions on Electronic Raman Scattering of Graphite in High Magnetic Fields
Y. Ma, Y. Kim, N. G. Kalugin +5
We report the observation of strongly temperature-dependent, asymmetric spectral lines in electronic Raman scattering spectra of graphite in a high magnetic field up to 45 T applie…
